‘Track Changes’ is a powerful feature for collaborative document editing. When enabled, it records every change made to the document, including insertions, deletions, and formatting adjustments. Each contributor’s changes are displayed in a unique colour, and the original text is shown with strikethroughs for deletions or underlines for additions.

This feature allows for easy review, acceptance, or rejection of individual changes and is particularly useful in team projects or when editing drafts.

To protect a Word document, go to the ‘Review’ tab and select ‘Protect Document.’ Here, you can restrict editing, which prevents others from making changes unless they know the password. You can also mark the document as final to prevent further editing, encrypt it with a password to restrict access, and control permission settings using a document management service like SharePoint.

Microsoft Word’s features encompass a wide range of functionalities. Key features include advanced text formatting (like font style, size, colour, and paragraph alignment), spell and grammar check tools for proofreading, mail merge for mass mailing, track changes and comments for collaborative editing, and the ability to insert multimedia elements such as tables, images, and charts.

Also, Word supports document templates, headers and footers, automatic table of contents, and hyperlink insertion.
